Sounds like mustard algae. Usually happens after a lot of rain or warm weather.
Organisms like algae, phytoplankton, and plants are typically found at the bottom trophic level of a food chain. They are important producers that convert sunlight into energy through photosynthesis, forming the base of the food chain.
Algae can appear at the bottom of a pool after shocking it because the shock treatment can kill off algae and other organic matter, causing it to sink to the bottom.
Yellow algae is as the description states yellowish in color. You can determine if you can see a yellow tint on the white or light surface of the plaster or vinyl. You can further determine algae by just brushing the yellow spots -- if it brushes off then it is most likely yellow algae. Mustard algae is similar but will be harder to brush off. The algae usually breeds on the shady side of the pool first then progresses to the rest of the pool depending on how long the pool has been neglected. K
The trophic level at the bottom in a food chain or food web is usually occupied by producers, such as plants or algae. These organisms convert sunlight into energy through photosynthesis, forming the base of the ecosystem's energy pyramid.
Dead algae.
Test your water for phosphates. Leaves contain it and phosphates are a growth nutrient for algae. Always use a sodium bromide based algaecide when dealing with yellow algae. (Yellow/brown/mustard algae is chlorine resistant.)
Algae eating fish include: bottom dwellers such as loaches, cat fish and plecs and many marine and fresh water tropical fish such as plecostomus fish.
Beacause chlorine is not being put in which is making it turn yellow :)
Chrysophytes are a group of mostly microscopic algae that are characterized by their yellow-green or golden-brown coloration, which is due to the presence of yellow and brown pigments in their cells. They are typically found in freshwater environments and play important roles in aquatic ecosystems as primary producers. Some chrysophytes are capable of forming harmful algal blooms under certain conditions.
Filamentous algae consists of long, thread-like strands made up of multiple cells joined end-to-end. These strands can be branched or unbranched, forming a mat-like structure. The cells of filamentous algae contain chlorophyll for photosynthesis and can reproduce by fragmentation or forming spores.
